The object of my hivention is the construction of a paddle-wheel in suchmanner that the blades shall always preserve a verticalposition.

The Vnatnreof my invention consists in securing tothe axle-off thewhee'l a se'riesof radial arms on bothsides of the blades.l In boxessecured on the outer ends of these arms, the axle of the blades has itsbearing. Onone end `of these axles is fastened a small cog-wheel, which`meshes in and `gears with a large cog-wheel securcdto the main shaft;as tlic `wheel. is revolved; it carries with it the large cogwheel,which in turn` revolves the `small cog-wheels 'attached to thel axle ofthe blades. These bladesnare so arranged that by means of the cog-wheelsthey will always preserve a vertical position.

To` enable others skilled in the art to m'akc and use my invention, Iwill `now `proceed to describe its construction and operation. y

A is the main shaft of the wheel. To this shaft A, are firmly attachedaseries of radial arms A1 A1, their number corresponding tothe numberofblades.

"On the outer ends of these radial arms are secured p metallicbearing-plates or boxes, ala, in `which worl the axlesB B of the bladesB' B. y l 0n` the near end of theseaxles B B, and in relation the radialarms `A1 A1, are secured small cog-wheels, c c, one on-eachaxle. f

These cog-wheels c e mesh in and gear with alarge r IMPROVEMENT INPADIWJLE-WHEELS. v I

cog-wheel, O, which is permanently secured to the main shaft A.

B' B' are the blades, and are convexed on both sides, as clearly shownin iig. 2, having on each end a metallic brace or holder, b b.

These blades may be constructed as clearly shown in igs.- 3 and 4,wherein the axle Bis a nearly-square bar of metal, the thickness of thepaddle-blade in its middle, so that, when the sections` or wings D D ofthe blade are tted to the axle B, they shall present l `a smoothanduniform surface.

VIhese` sections D' D' are held in their places by means of the slidingadjustable braces or holders D D and thumb-screws d il. n

YThe radial arms A' Al may be made tapering andconvexed, as clearlyshown iniig. 5, so as to enable them the more easily to eut the water intheir passage through it.

These arms A1 A1 may also be, causedto passth rough a slotted wheel orrim, A2, which will act as a stay or -wheels c c, and the deviceoperated by friction.

The axle of the main wheel O, and also that of thc small cog-wheels c c,should rest in adjustable boxes.

` Having thus fully described my invention,

What I claim therein as new, and desire to secure by LettersPatent'ofthe Unit-ed States, is-

The shaft A arms -A1 Al, blades B B', and cogwheels C c c, when thewhole is so combined and arranged as to operate substantially asdescribed. In testimony whereof I have signed my name to thisspecification in the presence of two subscribing wit- NATHAN F. BARNES,GEO. L. HAYs.
